Constrained Ball, a Strange New Device for Straight Lines

If you remember, we presented a strange device on Freshome a while back. It was a wooden electrical ruler and we featured it because we considered it was something new that would interest architects out there reading our site. Today we would like to show you something similar. “Constrained Ball” was created by Korean designer Giha Woo and helps its user draw straight lines and measure their length at the same time, by displaying it on a tiny screen. The device is small, practical and has a great, appealing design. However, for those architects who crave for traditional measuring methods, this multifunctional pencil will probably be looked at with a doubtful eye, as this design means that the old ruler is no longer a necessity.
